FUG. When checking my tire pressure this morning I noticed a slice/tear in the sidewall of my rear tire.
It's about an inch long and 1/8 inch deep. Its depth is not "straight in" but at an angle.
FYI: that is a Metzeler Roadtec Z6 with about 1800 kms on it, bought in April this year.
QUESTION 1: Is this something I should worry about? (Probably yes!)
QUESTION 2: How could this have happened? Physical contact with some kind of sharp edge is a possibility, for sure. What about stress under load? I have ridden at Boundary Bay 3 (?) times on these, with tire pressure at 30 psi. They have done very well for me (little/no chicken strips).
